LOOM.

SPECIFICATION forming part of Letters Patent No. 618,789, dated January 31, 1899.

Application filed October 6, 1898. Serial No. 692,819. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES M. DAY, of Hopedale, county of Worcester, State of Massachusetts, have in vented an Improvement in Looms, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings representing like parts.

This invention relates more particularly to that class of looms wherein a plurality of filling-carriers are automatically transferred one by one from a filling-feeder to the shuttle upon failure of the filling, such a loom being shown in United States Patents Nos. 529,940 and 529,942, dated November 27, 1894; and this invention has for its object the simplification and improvement of means for detecting the improper positioning of the shuttle in the sh uttle-box and upon such detection preventing the transfer of filling. I

Another form of shuttle-detector similar in some respects to my present inventionforms the subject-matter of United States Patent No. 568,455, dated September 29, 1896, to which reference may be had.

Figure 1 is a partial end elevation of a loom with my invention applied thereto, the outer or right-hand end of the filling-feeder being omitted. Fig. 2 is a sectional view of the loom, taken inside the filling-feeder mechanism, the lay being shown as in its forward position; and Figs. 3 and at are details to be referred to.

The loom-frame A, breast-beam A the lay A having the bottom of its shuttle-box S Fig. 1, cut away below the self-threading shuttle S, the filling-feeder comprising connected plates suitably shaped to receive the ends of the filling-carriers b, Fig. 1, and mounted to rotate on the stud a", the stud f, the transferrer f, mounted thereon and having the forked depending end f and a projection 21, the arm f, provided with the tip-supporting device f and the shaft d, adapted to be rotated by the movement of the weft-fork in the absence of the filling, are and may be all as represented in said Patent No. 529,942.

An arm d is secured to the rock-shaft d and is connected to one end of a spring 01 its other end being attached to the loom-frame,

and a link (1 is jointed to the arm d the upper end of the link having a longitudinal slot d entered by a pin or stud c on one of the arms 0 of a hub or sleeve 0, mounted rotatably on the stud f and having a second upturned arm 0 To this arm one end of an adjustable link 9 is pivotally connected, the other end of the link being jointed at e to a short upturned arm is of a hub K, mounted on the shaft or stud a projecting from the stand a", which supports the filling-feeder, as shown in Fig. 2.

A depending arm k secured to or forming a part of the hub is, is bent laterally at its lower end 70 and forms the shuttle feeler or detector.

By mounting the feeler or detector on the center of rotation of the filling-feeder the parts are brought into better working position and fewer and simpler parts can be employed, it being understood that the end 10 of the detector is turned toward the lay to engage the shuttle if the latter is improperly positioned inthe shuttle-box.

As in Patent No. 568,455 a rocker-stud m, Fig. 4, having a disk-like head m, is mounted on the end f of the transferrer, a spring 3 normally tending to turn the stud in the direction of the arrow 10, Fig. 1, the stud mhaving an arm m with an ear m on one side and a projection m on the other side, while a notched dog m adj ustably held on the arm m is adapted to be engaged by a bunter C on the lay when a filling-carrier is to be transferred to the shuttle.

A third outwardly-extended and downturned arm 0 on the hub c has attached to its extremity a downturned finger n which extends down over the lug m on the arm m (see Fig. 1) and at times controls the latter.

When the loom is running properly, the dog m is out of the path of the hunter 0, and the rock-shaft d holds the link 01 down, and the arm a is thereby elevated, with the finger ntoward the front of the loom to thereby act on the lug m and maintain the dog m in inoperative position, the finger n thus forming a detent for the dog. When the filling fails, however, the rock-shaft d' will be turned, elevating link 01 and permitting the hub c and its arms to turn on the stud f, so that the spring .9 immediately turns the stud m to throw the dog 11? into position to be engaged by the hunter (3 when the lay beats up. The movement of the arm m by its spring causes the lug m to move the finger n inward, depressing the arm 0 and rocking the hub c to operate through the link e and move the shuttle feeler or detector 70 across the inner end of the shuttle-box, so that if the shuttle is properly positioned the hunter will engage the dog m and operate the transferrer f.

Should the shuttle be improperly positioned, it will meet the endk of the feeler as the lay heats up and will swing it on its fulcrum, moving the arm 70 in the opposite direction, and through link a and arm a the hub 0 will be turned to swing the arm (3 outwardly, thereby causing the finger n to engage the lug m and rock the arm m oppositely to the arrow 10, Fig. 1, depressing the dog m out of the path of the hunter.

Inasmuch as the transferrer is only operated when the dog is engaged by the hunter the transferrer will not be operated to transfer a filling-carrier to the shuttle when the improper positioning of the shuttle in the shuttle-box.

2. In a loom, the lay; a rotatable fillingfeeder; filling transferring mechanism; a shuttle-feeler fulcrumed above the lay, in alinement with the axis of rotation of the filling-feeder, and connections between the said feeler and the filling-transferring mechanism.

3. In a loom, the lay having a slotted shuttle-box; a rotatable filling-feeder; a transferrer to transfer filling-carriers therefrom singly to the shuttle; means to operate the transferrer upon "failure of the filling; a shuttle-feeler fulcrumed above the lay in alinement with the axis of rotation of the fillingfeeder; and connections between said feeler and the transferrer-operating means, to pre vent operation of said means when the shuttle to be supplied with filling is not in proper position in the shuttle-box.

4. In a loom, the lay having a shuttle-box; a rotatable filling-feeder; filling-transferring mechanism operated by or through failure of the filling; a shuttle-feeler fulcrumed above the lay on the aXis of rotation of the fillingfeeder; and connections between said feeler and the filling-transferring mechanism, to prevent operation of the latter when the shut tle to be supplied with filling is not in proper position in the shuttle'boX.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

CHARLES M. DAY.
